Abstract
A portable battery˜powered sonic relay amplifies periodic beeping sounds from an alarm clock, smoke alarm, electronic watch or the like and analyzes the sound pulses in a logic circuit. If the sounds are periodically repeated high frequency sounds, a sound producer emits loud, low frequency sounds from a buzzer or the like, which may be heard more easily by a person with high frequency impaired hearing.
